What Is It?

Introverted Thinking (Ti) is an internal “compass” judgment function that allows us to make decisions based upon internal, subjective logical deductions.

Introverted Thinking often involves finding just the right word to clearly express an idea concisely, crisply, and to the point.

Using introverted Thinking is like having an internal sense of the essential qualities of something, noticing the fine distinctions that make it what it is and then naming it.

It also involves an internal reasoning process of deriving subcategories of classes and sub-principles of general principles. These can then be used in problem solving, analysis, and refining of a product or an idea. This process is evidenced in behaviours like taking things or ideas apart to figure out how they work. The analysis involves looking at different sides of an issue and seeing where there is inconsistency. In so doing, we search for a “leverage point” that will fix problems with the least amount of effort or damage to the system.

We engage in this process when we notice logical inconsistencies between statements and frameworks, using a model to evaluate the likely accuracy of what’s observed.

Who uses it?

• As a auxiliary function (supporting the dominant function) – ESTP, ENTP
• As a tertiary function – INFJ, ISFJ
• As an inferior function (most drained by) – ESFJ, ENFJ
